Microsoft Dynamics CRM VPC - August 2007 Edition August fix

There are two possible solutions to fix the VPC.

The first solution is to remove the host header on the Microsoft CRM website and change port 80 to 5555 within IIS. After this open regedit and do a find and replace in the registry on http://crm and replace it with http://ds-srv-01:5555. Go to start/run and type in IISRESET. After that you should access Microsoft Dynamics crm via http://ds-srv-01:5555.

The second solution is explained here: http://support.microsoft.com/kb/896861
